DRAINAGE-PUMP.

SPECIFICATION forming part of Letters Patent No. 667,091, dated January 29, 1901.

Application filed June 20, 1900. Serial No. 21,009. (No model.)

To all whom it may concern.-

Be it known that I, EDMUND MASTERS IVENS, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Drainage-Pu mp, of which the following is a specification.

This invention is in the nature of an improved low-lift drainage pumping mechanism particularly adapted for draining off low lands by lifting the water over a levee; and it primarily has for its object to provide a pumping mechanism of this character of a very cheap and inexpensive construction that can be readily set up in position for use and which will effectively serve for its intended purposes.

In its general make-up my invention comprises a lift box or flnme adapted to be conveniently set up upon the inside of the levee and have its discharge end extended upward and projected over the levee, a double suction-pump secured upon the lower end of the box at a point below the ground-line of the surface to be drained and having outlets at diametrically opposite sides, whereby to provide a double discharge into the box, and which is so arranged as to balance the water column automatically.

My invention also comprehends a novel construction of parts, including a peculiar correlation of the lift-box, the pump proper, and its shaft, means for balancing the pumpshaft and for providing for an easy and quick adjustment of the pump-shaft drive-pulley, whereby the same will raise up or down on the shaft, so as to come properly in line with the-driving-engine, which in. practice rests upon the ground-line of the plantation or surface to be drained.

My invention also embodies certain details of construction and peculiar combination of parts, all of which will be hereinafter made clear in the description, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which- I Figure 1 is a vertical section of my invention, parts being in elevation, the same illustrating the invention as applied for use. Fig.

2 is a horizontal plan, partly in section, takenpractically on the line 2 2 of Fig. 1. 'Fig. 3

is. a vertical section of the doubleacting pump devices, taken on the line 3 3 of Fig. 2.

In its practical arrangement my improved pumping mechanism is preferably located adjacent the inner side of the levee and at a low point of the surface to be drained or in a collecting-Well extended below the normal ground-line of the said surface or field.

The framework of the pumping mechanism comprises a wooden box 1 and also includes the vertical supporting-beams 2, the lower ends of which extend below the box 1 proper, and the said lower ends connect with and are braced by horizontal timbers 3, which timbers, together with the vertical beams or studs 2, form a suitable supporting-base for the pumping mechanism proper.

On the score of economy all of the framing is constructed of rough timber and all of the iron-work, excepting the upper bearings for the pump-shaft, is fitted upon the lower end of the box 1, which adds rigidity to the structure and provides for the economical and quick assembling of the several parts when setting up the pumping mechanism.

The pump 4. is a centrifugally-acting one and is disposed horizontally under the bottom of the box 1. This pump instead of having the usual single discharge is formed of two discharges 6 6 disposed at diametrically opposite sides, so that the rotation of the pumpdisks will effect a uniform discharge of the water in opposite directions into the outlets 6 6 and from them into the box 1.

The outlets or discharge-pipes 6 6 each connect with the bottom of the box 1, and each discharge empties through an opening 1 in the box 1, said openings 1 being each equipped with a back flap-valve 7 7, which serves to check the backflow of the water column lifted into the box 1 when the pump stops.

The pump 4 has inlets 8 on the upper and lower sides of its casing, so as to provide for balancing the water column automatically on each side of the disk.

9 indicates the piston-carrying shaft, mounted to turn in glands 10 10 connected to the pump-casing, and a gland 11 upon the upper end of the box 1, the extreme upper end of the said shaft being journaled in ball-bearings 12 to reduce friction and also to permit of a slight free vertical movement of the said shaft, the reason for which will presently appear.

The disk 9 may be of any approved construction. Preferably, however, the same is formed of two longitudinal sections arranged in the manner shown in my Patent No. 632,577, dated September5, 1899, so as to permit bringing the blade portions 13 close up to the casing-walls, as conditions may make necessary. In my present arrangementof pump, however, the disk is held to rotate in a horizontal plane, and to prevent the disk-blades grinding upon the lower edges of the casing the said disk is balanced in such a way as to maintain a proper running position within the casing with the opposite edges of the blades running uniformly in their relative arrangement to the walls of the casing, and for such purpose the disk after its blades have been properly adjusted as desired is keyed fast to the shaft, and the lower end of the shaft instead of being mounted on the step or fixed bearing, as is usual, is supported on the bearing-block 15, mounted upon the lever-bar 16, which is pivotally secured at one end to one of the cross-beams of the frame, its free end having a pivotal connection with the lower end of the vertically-projecting adjusting-rod 17, the upper ends of which pass through a bracket 18, fixedly held upon one of the vertical beams 2. The upper end of the rod 17 is screw-threaded, and upon the said end is mounted aspiral spring 20, which rests upon the bracket 18 and has its upperend arranged to engage with an adjusting-wheel 19, fitted upon the threaded end of the rod 17, the proper adjustment of which will increase or diminish the tension of the spring 20 and effeet a greater or less lift action of the rod 17. By supporting the pump-shaft on the adjustable yielding bearing,as shown and described, the pump-disk will be positively held from grinding on the bottom of the pump-casing and also balanced upon the water-pressure against the top thereof. The spring 20, the rod 17, and the wheel 19, which in practice is disposed at a point above the water-line, offer a quick and eifective means for properly setting the pump-disk and to balance it relatively to the water-pressure upon it, and in consequence it will at all times keep the said disk running uniformly.

The upper end of the box 1 terminates in a vertical channel a,which empties into a fin me Z), that projects over and rests upon the top of the levee, as shown, said supporting portion of the entire apparatus serving to brace the same to produce a stable structure, it being understood that in practice the fiume may be suitably braced by any well-known means upon the top of the levee.

By reducing the upper end of the lift chamber or box 1, as described, it will be noticed that ample room is provided for fitting a drivepulley 21 upon the shaft 10 mounted upon that part of the shaft held between the upper gland and the ball-bearings. This provides ample space for allowing for a free vertical movement of the pulley upon the said shaft 10, keyed upon the said shaft, the purpose of which is to permit adjusting the pulley up or down to provide for properly belting it with the driver-pulley upon the engine mounted upon the ground-line of the plantation or field to be drained.

In the practical construction of my pumping mechanism the pump-shaft has a slight free vertical movement in its hearing at the top to compensate for the slight balancing of the lower end that carries the piston.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the manner in which my pumping apparatus operates will be readily understood.

By referring to Fig. 1 it will be noticed that as the pump is disposed in a plane below the normal ground-line of the field or surface to be drained it follows that so long as there is water upon the said surface the pump can be operated to lift the same over the levee, which result is accomplished quickly and uniformly by reason of the pump having two discharges emptying at diametrically opposite points into the box 1, it being manifest that as the water rises in the said box 1 up to the fiume it will be constantly lifted over the levee during the continued operation of the pump until all of the water on the surface to be drained has been discharged.

Should during the operation of drainage the pump stop, the water column held within the box and fiume will be maintained and the water stopped from running through the pump by reason of the check-valves below the openings in the bottom of the box. 1.

My invention is of a very simple character, and the parts are so arranged that it is only necessary in shipment to send the pump, as the boxing and framing can be constructed by any person of ordinary skill to suit the requirements of the pump.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is- I 1. In a pump mechanism as described, the combination with the pump-casing having suitable inlets and outlets, and the centrifugally-operating disk, together with its driveshaft, the yielding counterbalanced bearing disposed below the pump-casing, in which the lower end of the shaft is supported, and means for adjusting the tension of the said yielding bearing, substantially as shown and for the purposes described.
